1. EXPLORING SPACE NOTES:

2. What are the first things that come to mind when you hear the term “Space Exploration”? Why do you think people have always wanted to study and explore outer space? EXPLORING SPACE NOTES: Uummm…

3. EXPLORING SPACE NOTES: An American, Robert Goddard launched the first rocket in 1926. After World War II, the U.S.A. formed NASA to compete with the Soviet Union in the space race. NASA – National Aeronautics and Space Administration. NASA The first satellite launched was Sputnik 1 in 1957.Sputnik

4. Yuri Gagarin – 1 st human to orbit Earth. Yuri Gagarin 1969 – Apollo 11 lands on moon (USA ; Armstrong). Columbia – The first space shuttle launched in 1981.space shuttle 1998 the International Space Station started to be assembled by the U.S.A and Russia.International Space Station EXPLORING SPACE NOTES: STS 119 Timeline

5. Space Exploration Has Given Us New Viewpoints. Throughout history, the study of stars and planets has inspired new ideas. As we meet the challenges of space exploration, we gain valuable technology. WHY IS EXPLORING SPACE IMPORTANT? NOTES:

6. Space science has advanced knowledge in other scientific fields, such as physics. For example, observations of the Moon and other bodies in space helped scientists understand how gravity works. Scientists figured out that the same force that causes an object to fall to the ground causes the Moon to orbit Earth. WHY IS EXPLORING SPACE IMPORTANT? NOTES:

7. Finally, the study of other worlds can teach us about our own. Earth has changed considerably since its formation. By comparing Earth with different worlds, scientists can learn more about the history of Earth’s surface features and atmosphere. WHY IS EXPLORING SPACE IMPORTANT? NOTES:

8. Surface Features Exploration of other worlds has helped us learn about the impacts of space objects. When an object strikes the surface of a larger object in space, it explodes and leaves behind a round pit called an impact crater. WHY IS EXPLORING SPACE IMPORTANT? NOTES:

9. Atmosphere We are also learning about Earth’s atmosphere from space exploration. Earth’s temperature allows liquid water to remain on the surface. Mars and Venus, the planets closest to Earth, have no liquid water on their surfaces. By comparing Earth with those planets, we can see how liquid water has affected the development of Earth’s atmosphere. WHY IS EXPLORING SPACE IMPORTANT? NOTES:

10. Satellite Views of Earth One of the most important benefits of space exploration has been the development of satellite technology. Satellites collect data from every region of our planet. The data are sent to receivers on Earth and converted into images. Scientists have learned from the space program how to enhance such images to gain more information. WHY IS EXPLORING SPACE IMPORTANT? NOTES: Satellite

11. Weather satellites show conditions throughout Earth’s atmosphere. Images and data from weather satellites have greatly improved weather forecasting. Scientists can now provide warnings of dangerous storms long before they strike populated areas. WHY IS EXPLORING SPACE IMPORTANT? NOTES:
